3,032,832 SLIVER COILHNG MECHANISM John S. Dudley, Douglas, Mass,assignor to Whitin Machine Works, Whitinsvilie, Mass, a corporation atMassachusetts Filed .luly 25, 1958, Ser. No. 751,073 3 Claims. (Cl.19-159) This invention relates to coilers for use with carding machines,combing machines, drawing frames, or with other machines which produce asliver of textile fibers that is to be coiled into a can. The inventionis also applicable to coilers in which a plurality of slivers are coiledinto a single can.

It is one object of the invention to provide a stationary member havinga defined passageway below the calender rolls, to assure that the sliverfrom the calender rolls will be accurately conducted into the coilertube. Another object of this invention is to provide a fixed coilerplate having an anti-friction bearing for supporting the coiler head, sothat the coiler mechanism can be operated with less power and at higherspeed.

The invention further relates to arrangements and combinations of partswhich will be hereinafter described and more particularly pointed out inthe appended claims.

A preferred form of the invention is shown in the accompanying drawing,which is a sectional elevation showing the invention.

The usual coiler plate is secured to a fixed support M and provides abearing for the coiler head '11. The coiler head gear is indicated bythe numeral 11a. Calender rolls 12 and 13 are rotatable about fixed axesabove the coiler head 11 and receive sliver from a trumpet 14 in a fixedsupport 15. A portion of the sliver can C is shown below the coiler head11.

The anti-friction mounting for the coiler head 11 consists of an outerrace 20 that has a snug or push fit in a recess 21 of the fixed coilerplate 10, and which is held therein by an annular ring 22 that is fixedto the coiler plate by screws 23.

The inner race 24 has a downward extension 25 that is freely rotatablein the opening 26 of the coiler plate 10. Secured to the inner race 24by screws 27 is the coiler head 11, and the portion 28 of the coilerhead 11 is a push fit in the bore of the inner race 24.

Lubricant in the ball bearing is prevented from escaping downwardly by asealing ring 29. The flange 30 of the ring 22 acts as a deflector toreturn any lubricant that may escape upwardly, as well as to prevent flyor lint from getting into the bearing.

A fixed member 40 for conducting the sliver into the coiler tube 41 hasan opening 42 and side portion 421: that extend upwardly into the bitebetween the calender rolls 12l3. The member 40 is supported and fastenedby a screw 43 in the hub portion 44 of a bracket 45 that is clamped by ascrew 46 to a fixed rod 47.

Replacing the member '40 by one with a different size of opening orpassageway can be easily and quickly accomplished by loosening the screw46 and sliding the bracket 45 along the rod 47 until its hub 44 is clearof the tube 41. The bracket 45 can then be swung clockwise so that themember 40 can be removed without interference with the calender rolls.

tent

When a new member 40 of the required size of passageway is placed in thebracket, the bracket is returned to its operative position and againclamped to the rod 47.

The coiler tube 41 is soldered or otherwise secured to a bracket 58 thatis fastened to the head 11 by a bolt 51.

Should it be necessary to remove the head 11 from the coiler plate 10,the bolt 51 is first unscrewed, and the combined tube 41 and bracket 50is lifted out from the head 11. The screws 27 are then unscrewed fromthe inner race 24, after which the head 11 can be lifted out of thebearing. If the bearing has to be removed, the screws 23 are unscrewedand the ring 22 is removed, after which the entire bearing can be liftedout of the plate 10*.

A usual pair of calender rolls having a fixed axial guide memberassociated therewith is thus provided. A coiler head is also providedhaving an improved bearing support and conveniently removable therefrom.Special provision is made to protect the bearing from lint and toprotect the sliver from dirt.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:

1. In a sliver coiling mechanism having a rotatable coiler head with asloping coiler tube secured thereto and calender rolls to supply asliver to the coiler tube, the combination of an annular fixed sliverguide member adapted to be disposed between the calender rolls and thecoiler tube, a bracket, means to secure the bracket to the sliver guidemember, a fixed rod parallel to the axes of the calender rolls, andmeans to mount the bracket on the rod for movement along the axis of therod and for rotary movement about the axis of the rod.

2. In a sliver coiling mechanism having a coiler head with a coiler tubesecured thereto and calender rolls to supply a sliver to the coilertube, the combination therewith of an annular fixed sliver guide memberdisposed between the calender rolls and the coiler tube and extendingsomewhat into the space between the rolls, a bracket supporting saidguide member, and means slidingly mounting the bracket and with it saidmember for movement of the bracket and member in a direction parallel tothe axes of the calender rolls while continuing support of the bracketand member for removal of the sliver guide member from between thecalender rolls and the coiler tube.

3. A mechanism according to claim 2 in which the means mounting thebracket supports it also for movement in a direction perpendicular to aplane through the axis of the calender rolls.
